[Closed] Li-Ion 18650 protected Recharge batteries with connection wires / lines

Hi all,
Trying to source a decent 18650 Li-Ion battery as a replacement for an exposure light.
can only find two really on WWWW that come with presoldered protection board and wires / connection lines for soldering in to joystick.
One is a samsung 2600 :

and the other a Emmerich 2600 :

Research suggests exposure use Sanyo batteries and some of the top performing ones are Panasonic / Xtar ? ?

Could buy batts with tabs and solder my own wires on but not keen on this route. Obviously want the best battery possible.
Anyone use anything else, anyone with any advice.

Have contacted Smudge (MTB BATTERIES) but he's busy with family stuff and dont want to keep bothering.

Thanks everyone.
